Front

What is the formula for finding the area of a triangle?

Back

Area = 1/2 * base * height.

Front

What is the formula for finding the area of a rectangle?

Back

Area = length * width.

Front

What is the formula for finding the area of a parallelogram?

Back

Area = base * height.

Front

What is the formula for finding the area of a trapezoid?

Back

Area = 1/2 * (base1 + base2) * height.

Front

What is the formula for finding the area of a composite shape?

Back

Break the shape into simpler shapes, find the area of each, and sum them up.

Front

What units are used to measure area?

Back

Square units (e.g., cm², m², ft², yd²).

Front

How do you find the height of a parallelogram if you know the area and base?

Back

Height = Area / base.

Front

What is the relationship between the bases of a trapezoid when calculating its area?

Back

The area calculation involves the average of the two bases.

Front

What is a composite shape?

Back

A shape made up of two or more simple shapes.

Front

How do you calculate the area of a trapezoid with bases of different lengths?

Back

Use the formula: Area = 1/2 * (base1 + base2) * height.
